In the book Pianism by Aiko Onishi (a book I bought following Pianostreet's forum recommendation) the author mentions several forms of producing different tones and "colors", from colorless (just a vertical, even press of the key), to harmonious (a curved, sliding motion), singing and some others tones. She says that in order to produce a singing tone one ought to "mold" the key while doing a curved motion, which means that the first joint should "go down on the key with accelerando using the ball of the finger similar to molding clay or hard bread dough". She also mentions the while doing most of these tones (except when louder sounds are required) one should not touch the keybed, but rather only exert force only until the key reaches the tone spot (also called time spot, key spot or after-touch), relaxing the finger after that. Though the book sounds theoretically reasoned, I've googled the autor and some of the terms she uses but found nothing, not even a single page about Ms. Onishi that isn't about her book, which makes me question the soundness of her techniques. I was hoping you could provide some advice and personal testimony regarding these techniques and whether it's worth spending one's piano time learning them.Thank you
In piano playing, I have honestly never thought of what joint of the finger does what.
Also, we musn't make too big a deal out of common things, like this convoluted description: "one should not touch the keybed, but rather only exert force only until the key reaches the tone spot (also called time spot, key spot or after-touch), relaxing the finger after that." The fact is you can't change the tone once you depress the key, so why would you keep exerting pressure? It is just common sense.
There's always one isn't there.
Regarding the subject: Here's what Matthay said...quoting from his work:#1 The more speed in the string the louder the resultant sound. Only by making the KEY (and the String therefore) move quickly can you produce loudness. There is no other way. #2. The Piano Key is a leverage system, a machine, to enable you to get speed with the string, and to ensure dynamic control--of the exact speed (or tone) desired.#3 Open your piano lid, so that you can watch the hammerheads. Now put your finger upon a key, and notice when you depress the key its 3/8 of an inch, that the hammer head moves about five times that distance, and therefore exaggerates by five times, the speed with which you depress the key.#4 Also notice that it falls back the instant it has reached the string and has set the same into vibration (or movement) --although you may be keeping the key depressed afterwards. This is owing to the hopper device which allows the hammer to rebound from the string. Without this device the hammers would be jammed against the string and all tone destroyed. ...he goes on to say that "good tone, ease of production and control of tone can only be obtained by gradually pressing the Key into Motion. Only in this way can you obtain perfect control over tone, good "singing" tone and good quality of tone. Bad tone, and lack of control over tone, arises when the Key is jerked down by a too suddenly applied impulse."In his book Musical Interpretation, Matthay talks about the TIME SPOT for each note you play and being aware of this spot is essential in order to play musically and with beautiful sound. You, the pianist INTEND every note you play. that was his Credo.
